This work offers an interpretation to the unexpected magnetic field orientation found inside Titan's induced magnetosphere for Cassini flybys where excursions into the magnetosheath have been confirmed prior and at the time of closest approach. This interpretation is based on the concept of ';fossil fields' described in previous works. In particular, we report the first observation of remnant interplanetary magnetic field lines in Titan's ionosphere during flyby T39, and the second observation of remnant Kronian field lines while Titan is in Saturn's magnetosheath during flyby T85. In these cases, the ages of the fossil fields agree with those previously reported for flyby T32.
